Remove the wheel containing the defeated tube. It may be advantageous to start by placing the bicycle within a home repair stand, held securely by the seatpost. Many types of how to patch a bicycle tube can be easily released to aid in tire repair, so be sure to disengage the brake, if necessary. Most modern wheels remove by means of Quick-Release QR skewers, pictured here, which pass entirely through the hubs, and have open and closed positions to secure them to the frame.

To remove the wheel, flip the lever to the "open" position. Hold the non-drive side nut of the skewer as you turn the lever counter-clockwise to loosen. Oftentimes, the wheel can be removed without completely unthreading the skewer.

Note the orientation of the two springs and skewer it enters from the non-drive patvh for ease of jow. Many other wheels will use a bolt-on standard, usually a 15mm bolt on a threaded axle.

Use a 15mm or adjustable wrench to remove these axle bolts by turning them counter-clockwise. How to check fedex shipment history higher-end bicycles have wheels that connect by means of a thru-axle TA system.

Like QR skewers, Thru-Axles run internally through the entire length of the hub. Thru Axles, however, thread into a special sleeve built into the fork or frame dropout. Removing these is as simple as turning the TA anti-clockwise, although each manufacturer may have special instructions. Using the tire levers, unseat the bead of the tire by running the lever along the inside of the rim.

With the first bead unseated, repeat the process to remove tybe second bead off of the rim. Examine the outside for the cause of failure.

The bead is the part of the tire designed to hold the tire to the rim. For more about this step, see how to replace a bicycle tube. After looking around the outside, remove the tube from inside the tire. Run your fingers lightly along the inside, checking for any sharp spines or staples.

If you are ro difficulty finding the hole, lightly inflate it and check by submerging under water. Escaping bicyc,e bubbles will point to the puncture. Once you have found the problem, use a metallic sharpie to mark the area. Using the sandpaper, lightly scuff the area surrounding the puncture. Be sure to scuff an area larger than the patch being applied. Apply the tube cement and smear it evenly over the scuffed area using a clean finger, or foil edge of the patch.

Make sure to spread tjbe to cover the entire affected area. This may take up to 10 minutes. It's a bkcycle too wet in the picture, so let it dry a bit longer. Choose an appropriately sized patch so as to completely cover the affected area. Remove the foil backing from the patch. Leaving on the transparent plastic covering, pztch the what is the recovery time for gastric sleeve surgery over the area, pressing the tube and patch together.

Holding firmly bicylce your thumb and forefinger, apply moderate pressure while how long does chantix take to work the patch in place.

This should take about 5 minutes. Leave the transparent plastic film on as it will help to resist abrasion. Pump up your tube a small amount, just enough to give it shape. Place the lightly-inflated tube within the tire. Using only your hands, roll the beads of the tire one at a time onto the rim until the tire is properly seated. Take care to install tires with the proper direction of rotation, when applicable. An arrow indicating direction of rotation can be found on the vicycle tire itself.

Once tbue, pump up the tube slowly to the desired pressure, checking for irregularities in the tire. If either bead is pwtch seating properly within the rim, deflate the tube, lubricate the beads of the tire with some soapy water, and reattempt inflation. If using a QR skewer, hold the drive side nut while turning the lever clockwise. Close the lever from the open to closed position, ensuring that the clamping ibcycle secures the wheel within the frame. After the bicycle has been sitting for 15 minutes or so, use the air pump to check the inflation pressure of the tire.

Yow it is the same, test ride the bicycle a short distance and then re-check the pressure. If it shows no signs of loss, it's good to go! The nose of a saddle, when mounted too high or low can cause rider discomfort. Mounted too high, a rider will feel extra pressure on the sit bones.

What do you do — walk all the way back to the start of the trail and head home or fix your puncture and finish like a champion? If you know how to identify and patch holes in your bike's inner tube and you take the precaution of carrying a simple patch kit with you any time you take a serious bike trip, you have the luxury of being able to make this choice rather than having it made for you.

Before you patch a bicycle tube, you'll want to remove the tube from the tire and locate the puncture, which you can do by inflating the tube and checking for holes. Once you've found a hole, mark it so it's easy to locate.

Next, apply glue around the hole, let it nearly dry, and press the patch into place. Alternatively, you can simply lay the patch over the hole if it's a non-glue patch. After the patch has set, feed the tube back into the tire and put the tire back on the wheel.

Part 1 of Remove the wheel from the bike. The first thing you should do for any flat is to remove the affected wheel. Check the side of the wheel at the center of the spokes. If you have a quick release which looks like a small lever , flip it over and spin it counterclockwise to loosen. If, on the other hand, you see a nut, you will need a wrench to loosen it. After this, disconnect the brakes, move the brake pads out of the way, and remove the wheel.

If you're dealing with the rear flat, you'll also have the chain and gears to deal with. Put slack in the chain by shifting into the smallest set of gears. Loosen the quick release or unscrew the nut holding the wheel in place as normal. Use tire levers to remove the tire. When you've successfully removed the flat wheel, take the outer tire off. To do this, it can be helpful to use a sturdy, non-metal prying tool. Bike shops sell small, specially-designed tools called tire levers for this purpose.

Whether you use a tire lever or another tool, be careful not to pinch the tube and cause further damage as you work the tire away from the wheel. You can leave one lip of the tire over the wheel rim when you're done to make re-installation easier. These are likely to damage the rim and may even puncture the tire. Locate the hole that's causing the leak. When the tire has been removed, pull the flat tube out from the tire and pinpoint the site of the puncture.

This can be done in several ways — a few are listed below: [2] X Research source Inflating the tube 3 to 4 times its normal size and visually checking the surface of the rubber for holes. Mark the hole in the tube. Flat-causing tire punctures can be surprisingly small. Once you've found one, you don't want to lose it! If you're using a glue-on patch, make your mark large so that you can still see it after you've smeared on the glue.

If you don't have chalk in your patch kit, a ballpoint pen or any other sort of writing utensil will do. However, chalk or a silver sharpie is preferable because it's easier to see on black rubber than blue or black pen. Part 2 of Remove any foreign objects from the hole. Once you find the hole, carefully check to see if it was caused by a foreign object like, for instance, a piece of broken glass, a sharp rock, etc.

You don't want the same object that caused the flat in the first place to re-puncture your tire because you didn't see it. Sand around the hole if necessary. Different types of patches work in different ways — some require glue, while others do not, and some require sanding, while others can stick to the smooth rubber of the inner tube with no trouble.

Consult the directions included with your patch kit. If you're directed to sand, use a small square of sandpaper to rough up the area around the hole about as wide as the patch to be used.

Making the rubber a little less smooth can improve the sticking power of certain types of adhesives. If you're unsure about whether or not to sand, lightly sanding is unlikely to hurt most patches' ability to stick to the tube, so you may want to sand just in case.

Apply the patch. Next, stick your patch over the puncture hole according to any included directions. Some patches require glue, while others can stick to the tire on their own — while the latter are more convenient, they can sometimes be less reliable.

General directions for both types of patches are below. If the directions included with your patch differ from these, follow your instructions, rather than these directions.

Glue patches: Apply the glue or rubber cement to the tube around the puncture hole, wait for the glue to set many glues must dry until they are no longer tacky — consult any included directions for more information.

Finally, place the patch on the mostly-dry glue and hold firmly in place for a few minutes until it has sealed the leak. It may take about 24 hours to for the glue to dry completely, but it may be dry enough to use the bike in about 5 minutes.

Know when replacing the tube is a smarter choice. In situations where you have a severely damaged tube, you may want to avoid wasting your patch by opting to simply replace the entire tube instead. Tubes that have serious damage may not stay inflated long enough with the patch to make using it worth it, making full-on replacement a better choice. Part 3 of Replace the tube in the tire. After your patch has had an opportunity to set, carefully feel around the inside of the tire for any protruding foreign objects, such as metal wire, which may have caused the puncture.

Take your repaired tube and carefully lay it in the hollow inside portion of the tire. This is usually easiest if you inflate the tube slightly and slide one side in first, then work the rest in as necessary. When you're done, double-check to make sure none of the tube is hanging out of the tire.

Make sure the inflation valve is pointing inward away from the tire when you lay the tube in the tire so that you can eventually inflate the tube. Work the tire and tube back onto the wheel. Next, use your thumbs to slide the tire which contains the partly-inflated tube back onto the wheel. Press the outer lips of the tire over the metal lip of the wheel so that they "lock" securely in place, being careful not to pinch the tube between the tire and the rim.

You may need to use your tire lever or prying tool to help you with the very last part of the tire, which can often be tricky to get over the lip of the wheel. Note that some high-end bike tires are meant to only turn in one direction. In this case, the intended direction of rotation will usually be indicated by small arrows on the walls of the tires.

Don't install the tire backwards! This can reduce the bike's performance and cause the tire to wear improperly. The lidless inflation valve should slide through a circle-shaped hole in the wheel so that it can be easily accessed for pumping.

Inspect the bead and pump up the tube gradually to let the tube and tire settle. Make sure the tube is not sticking out between the tire and the rim before you start to pump, or the tube might explode. Next, grab an automatic or hand-operated pump and start putting some air in your tire. Go gradually to allow the tube to shift and settle within the tire as it expands. When fully-inflated, give the tire a squeeze, let the bike sit for a few minutes, then squeeze the tire again.

If it feels about as firm the second time as it did the first time, you're ready to ride! If you're worried about the tube settling improperly within the tube, feel free to inflate it before re-installing the tire on the wheel.
